ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 330,652, dated November 17, 1885.

Application led September 12, 1885. Serial No. 176,937. (Model.)

To @ZZ whom it mag/concern:

Be it known that I, EDWIN V. WHITAKER,

' a citizen of the United States, and a resident of Gloversville, in the county of Fulton and State of New York, have invented certain new and useful Improvements in Roller-Skates; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure l is a perspective view of my improved roller-skate, and Fig. 2 is a longitudinal vertical sectional view of the same.

Similar letters of reference indicate corresponding parts in both the figures.

My invention has relation to that class of rollerskates in which the frames for the rollers are pivoted to turn in a horizontal plane, and provided with reaches pivotally connected to each other, and which have a straight spring secured to the under sides of the roller-bear# ing frames and to the reaches at their points of unionjy and it consists in the improved construction and combination of parts of the same.

In the accompanying drawings, the letter A indicates the foot-board, which is provided with the usual toe-clamps, B, and heel-clamps C, which may be of any desired construction, or with any other suitable form of fastening. This foot-board, which may be made in one, as shown in the drawings, or in two partsone heel portion and one toe portion-is provided at the heel portion with two downwardly-bent lips, D and E, having perfora-l tions F, through which the screw G, which operates the heel-clamp, passes, and the toe or sole portion of the foot-board is formed with two downwardly-bent lips, H Aand I, through perforations J, in which lips a longitudinal screw, K, passes. A longitudinal bar, L, has perforated upwardly-projecting lips or lugs M, which bear against the inner sides of the downwardly-projecting lips of the foot-board, and the longitudinal screws pass through the perforations in the said lips and rockin the same, allowing the foot-board to rock upon the longitudinal bar. The longitudinal bar is provided at its ends with downwardly-projecting cylindrical lugs N, having an axial perforation, O, andan annular groove,

P, in the lower end, and these lugs 1"1t into cyf. lindrical sockets Q, projecting upward from the roller-bearing frames R. The sockets have annular grooves S in their bottoms, and have axial perforations T, and anti-friction balls U are placed in the annular grooves of the sockets and fit into the annular grooves of 6o the cylindrical lugs, forming an anti-frictional support for the saine. If desired, annular washers may be interposed between the downwardly-projecting lugs land the sockets, into which they are inserted, as shown at w, to compensate for wear against the inner sides ofthe cylindrical sockets. A bolt, V, having a iat perforated head, W, which rits into a recess, X, in the roller-bearing frame, passes up through the axialperforations of the socket 7o and lug, and has a screw-'threaded perforation, Y, in its upper end, into which passes the end of a screw, Z, the head of which bears against the upperside ofthe longitudinal bar, thisscrew securing the lug into the socket and the entire roller-bearing frame to the end of the'longitudinal bar. lThe perforation through which the axle A' of the rollers B' passes registers with the perforation in the head of the bolt V, so

that the said axle will hold the bolt in position. 8o The roller-bearing frames have inwardly-projecting screw-threaded sockets C', into which rit the screw-threaded ends of the reaches D' and E', which are respectively formed with a flat vheadfhaving a perforation, F', and with 8 5 two longitudinally-slotted lips, G', between`i which the flat head its and is retained by a bolt, H', which passes up through the slotted lips and the perforation inthe head, and which is provided with a transversely-perforated oo head, I', and with a transverse perforation, J', in its upper end for Athe insertion of a pin or split key, K'. 'Ihe heel-piece is provided with a downwardly-projecting socket, L',

which passes through a transverse aperture,

M', in the longitudinal bar, and the upwardlyprojecting end of a bolt, N', ts into this socket, while its lower end is formed with anA eye, O', which fits upon the inwardly-projecting socket portion of the rear roller-bear- 10o longitudinal perforations Q', and a rod, R', of

rspring-wire passes through these perforations and through the perforated head of the bolt which unites the reaches.

It will now be seen that when the foot-board is tilted to one side or the other the telescoping post projecting from the heel-piece down to the rear reach will turn the rear roller-bearing frame to the side, which again, by reason of the pivotally-united reaches, will turn the other frame, so that the rollers, while being in a horizontal plane at the same time will stand at angles to each other, guiding the skate in a curved direction, and the spring at the under sides of the roller-bearing framesV and passing through the pivotal bolt will offer sufficient resistance to prevent the foot-board to tilt too far down to a side or the frames and rollers from turning too far.

The foot-board may, as before stated, be di` vided into a sole portion and a heel portion, in which case each portion will have its separate telescoping post extending down to the reach, and where the foot-board is made in one piece the telescoping post may be equally as well extended from the sole portion as from the heel portion. 1

The anti-friction balls between the sockets and cylindrical lugs may be dispensed with where cheapness is more desirable than reduction of resistance, and either washers interposed between tlie lugs and sockets; or their meeting surfaces may bear directly against each other with nothing interposed.

By extending the reaches in their sockets they will be enabled to be turned farther out to the sides, thus increasing the yielding properties of the skate, while naturally the con-V tracting of the reaches will accomplish the opposite effect.

The spring rod or bar is retained in its perforations by means of a small set-screw, S', passing into the perforation in the head of the pivotal bolt for the reaches, bearing with its end against the spring.

By having the telescopic post project-ed from the heel portion of the foot-board the weight of the body thrown upon the side of the foot when turning or describing a curve will be thrown upon the rear rollers exclusively, and will in this manner not stop the speed, as when the weight of the body is thrown upon the toe, which will stop the speed considerably.

Havingthus described my invention, Iclainl and desire to secure by Letters Patent of the United Statesl. In a roller-skate, the combination of a longitudinal bar, roller-bearing frames pivoted to turn horizontally upon the under sides of the ends of the same, and having inwardlyprojecting reaches pivotally and extensibly connected to each other, and a foot-board having a post projecting downward and movably attached to one of the reaches, as and for the purpose shown and set forth.

2. In a roller-skate, the combination of a longitudinal bar having downwardly-projecting cylindrical lugs at its ends, roller-bearing frames having cylindrical sockets receiving the lugs, bolts passing axially through the cylindrical lugs and sockets, reaches projecting inwardly from the roller-bearing frames and having their ends pivotally and extensibly connected, a spring-bar attached to the roller-bearin g frames and tothe uniti ng-bolt for the reaches, and a foot-board rocking upon the longitudinal bar and Vhaving a downwardly-projecting telescoping post movably attached at its lower end to one of the reaches, as and for the purpose shown and set forth.

3. In a roller-skate, the combination of a longitudinal bar having the rocking footboard attached to its upper side, and having two downwardly-projecting cylindrical lugs at its ends formed with axial perforations and with annular grooves in their lower ends,with roller-bearing frames connected by pivotally and extensibly united reaches, and provided with sockets for the lugs having axial perforations, and annular grooves in their bottoms, anti-friction balls placed in the grooves, and bolts passing up through the axial perforations and secured to the longitudinal bar, as and for the purpose shown and set forth.

4. In a roller-skate, the combination of the roller-bearing frames pivoted to swing horizontally, and having the inwardly-projecting threaded sockets and the downwardly-projecting perforated lugs, the reach having the perforated flathead and fitting in the socket of one roller-frame, the reach having the longitudinally-slotted lips and fitting in the other socket, the bolt passing through the slots and the perforated head,'and having a transversely-perforated head provided with a set? screw, and the spring-rod passing through the perforated lugs and through the. perforated head of the bolt, being retained by the bolt, as and for the purpose shown and set forth.

5. In' a roller-skate, the combination of a longitudinal bar having downwardly-projecting cylindrical lugs at its ends, roller-bearing frames having cylindrical lugs projecting upward, washers interposed between the said lugs. bolts passing axially through the cylindrical lugs, reaches projecting inwardly from the roller-bearing frames and having their ends pivotally and extensibly connected, a springbar attached to the roller-bearing frames and to the uniting-bolt for the reaches, and a footboard rocking upon the longitudinal bar and having a downwardly-projecting telescoping post movably attached at its lower end to one of the reaches, as and for the purpose shown and set forth. l

In testimony that I claim the foregoing as my own I have hereunto aiiixed my signature in presence of two witnesses.

EDIN V. WHITAKER.
